Evolution of Coblation

Coblation stands for controlled ablation. The technology uses radiofrequency in combination with low temperatures to “ablate” tissues, commonly using a saline rinse to wash away ablated tissues. The temperature of coblation instruments ranges from 60 to 70 degrees Celsius, whereas electrocautery instruments may exceed 400 degrees Celsius. It has been proposed that this method causes less bleeding and postoperative pain than cold steel excision, and electrocautery, respectively. Coblation is also commonly used as a method for tonsillectomy.
